Hogan's Heroes aired on CBS from 1965 to 1971 and was set in Stalag 13, a German prisoner of war camp during the Second World War. Bob Crane starred as Colonel Hogan, who ran secret operations under the nose of commandant Colonel Wilhelm Klink, played by Werner Klemperer. Klink's stern military phrases became part of the show's running comedy because his authority was constantly undermined. Short excerpts like this one later circulated online as reaction sounds, reused for mock-serious endings long after the series finished.
